Yes there would be significant gains with the head mods even NA. Probably NA would benefit more with some cam grinding also where the cams are pretty aggressive already for boosted applications. |
If I knew a built NA engine would reliably make about 250whp it would be something I would definitely consider. My goal would be to build a reliable and good handling TT3/ST3 car to compete in NASA, so I would be looking for a weight to power ratio of somewhere around 10:0 to 9:0. I figure it wouldn't be too hard to get the car down to 2400-2500lbs with me (200lbs) in it. As it stands right now, my current idea for a project car with more NA power is an MR2 Spyder with a 2GR-FE swap.
